Embodiment approach

[0040] As an embodiment of the present invention, the A component is a cationic surfactant.

[0041] As an embodiment of the present invention, the cationic surfactant is a cationic surfactant containing imidazole.

[0042] As an embodiment of the present invention, the hydrophobic chain of the imidazole-containing cationic surfactant is a long-chain hydrocarbon chain.

[0043] As an embodiment of the present invention, the preparation method of the cationic surfactant is as follows:

[0044] (1) After adding 24 mL of toluene and 24 mL of dimethyl sulfoxide into the reactor, add 15 g of imidazole, stir evenly and add 16 g of 50wt% sodium hydroxide solution, and reflux to react until no water is produced;

[0045] (2) Add 21.5g of 1,4-dibromobutane under stirring, heat up to 110°C and stir for 4 hours, then filter the filtrate while it is hot, distill off the solvent on a rotary evaporator, and place the filtrate in a beaker. Add 60mL of distilled water and leave it at room temperature ...

Embodiment 1

[0084] Embodiment 1: This embodiment provides a soil solidification agent, the soil solidification agent is divided into A component and B component,

[0085] The A component includes water, ethanol, tourmaline, component A cationic surfactant and small molecule polyol;

[0086] The B component includes polysaccharides, component B surfactants, biological enzymes, calcium carbonate, complexes, inorganic-organic complexes, water and ethanol.

[0087] Tourmaline: The said tourmaline was purchased from the Zhenying Mineral Products Processing Factory in Lingshou County. The type is fiber tourmaline, and the specification is 200 mesh.

[0088] Component A cationic surfactant: The component A cationic surfactant is a cationic surfactant containing imidazole, and its preparation method is as follows:

[0089] (1) After adding 24 mL of toluene and 24 mL of dimethyl sulfoxide into the reactor, add 15 g of imidazole, stir evenly and add 16 g of 50wt% sodium hydroxide solution, and reflux to reac...

Embodiment 2

[0104] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the weight ratio of the A component and the B component is 1:2.

Description

Technical field [0001] The invention relates to the technical field of solidifying agents, and more specifically to a biological enzyme composite soil solidifying agent and its use process. Background technique [0002] The traditional technique used for road foundations is the method of using cement to stabilize the gravel. To get rich, build roads first. With the development of economy, the road construction of all countries in the world has entered a stage of rapid development. There is no corresponding increase in road construction materials that meet the needs of road engineering. The total amount of sand and stone materials traditionally used in roads or construction has also been reduced year by year due to continuous mining. Some areas have even been exhausted, and the requirements for sand and stone resources in some areas are demanding. In contrast, a large number of building materials in demolition projects were discarded. [0003] In the past 20 years, soil solidific...
